Up Close With The Patek Philippe 175th Anniversary World Time Moon Refs. 5575G and 7175R (With Photos And Price)

For its 175th anniversary Patek Philippe combined its signature world time with a photorealistic moon phase, paired with a carefully detailed case that features sculpted, lyre-shaped lugs.

Of the four models Patek Philippe unveiled for its 175th anniversary, the Multi-Scale Chronograph and World Time Moon stand out for being relatively affordable – after all, the top of the line anniversary Grandmaster Chime costs 2.5 million francs. Unsurprisingly, they have garnered the most interest, particularly the World Time Moon, according to anecdotal evidence from Patek Philippe retailers. Made in both men’s and ladies’ variants (refs. 5575G and 7175R respectively), the World Time Moon is unusual in several respects. For one, it’s the first time in the modern era Patek Philippe is combining a world time with another complication. And the World Time Moon is also a very large edition, totalling 1750 pieces for both versions. Less obvious but also significant is the sculpted case form, illustrating the great strides Patek Philippe has made in its case making. There are two versions of the World Time Moon, the first being the men’s Ref. 5575G, in a white gold case measuring 39.8 mm across. This will be made in a surprisingly large edition of 1300 pieces with a price of 45,000 Swiss francs.

And in a smaller edition of 450 pieces, the ladies’ Ref. 7175R is in rose gold, with a 38 mm case and 70 diamonds of about 0.6 carats on the bezel. This will cost 50,000 Swiss francs.

Both versions of the World Time Moon are mechanically identical, equipped with the calibre  240 HU LU (short for heures universelle lune, translating as “world time moon”). The world time functions works exactly as it does with the regular world time: the button at 10 o’clock advances the display by an hour.  In short, it is the very traditional 24 time zone world time as invented by Louis Cottier and made famous by Patek Philippe, though also utilised by other brands. But in a nod to Patek Philippe’s anniversary, Central European Time is denoted by Geneva on the cities disc, rather than Paris as is convention.

In the centre of the dial is the oversized moon phase display, comprised of two glass discs. The lower disc is metallised (essentially a thin layer of metal coating) on its underside with a depiction of the night sky scattered with stars, as well as a very large moon, almost exactly as it appears from Earth, complete with craters and ancient volcanic plains.

Above that the second glass disc is clear, except for a kidney-shaped outline where the Patek Philippe logo is. This outline forms the shadow of the moon, allowing the age of the moon to be displayed. Continuing the astronomical theme, the hour hand is shaped like an elongated star, inspired by the Southern Cross constellation. While novel, the star-shaped hand is at odds with the relatively classical aesthetic of the watch.

Like the other models in the anniversary line-up the World Time Moon has a solid back. However, the movement inside is likely identical to the calibre 240 inside the conventional world time, which looks like this. 

Aesthetics and movement aside, equally notable is the case shape of the World Time Moon, particularly the lugs. Sleek and flowing, the lyre lugs are beautifully shaped and carefully formed. They are a world away from the simplistic case form of the World Time Ref. 5130 and 5131.

The increased detail and quality of the case form is not limited to this model, in general Patek Philippe has made notable progress in its case manufacture. A quick comparison of the Refs. 3970 and 5270 illustrate the same point – these are equivalent models two generations apart but with major improvements in the case quality.  The World Time Moon Refs. 5575 and 7175 are being delivered to Patek Philippe retailers right now, with a long waiting list for both. However, given the 1750 pieces made in total, the wait might not be as long as expected.

Up Close with the Patek Philippe Ref. 5539G Minute Repeater Tourbillon (with Original Photos & Video)

Unassumingly plain with a black enamel dial and spade hands, the Patek Philippe Ref. 5539G is an entry level watch of sorts, being the simplest hand-wound minute repeating wristwatch in the collection.

Introducing The Luminox 25th Anniversary Limited Editions For Singapore (With Specs And Pricing)

American watch brand Luminox marks its 25th anniversary with a pair of limited edition watches featuring tritium tube illumination, available exclusively in Singapore, Malaysia and Brunei.

Luminox began in 1989 as the supplier to the US Navy Seals of affordable, robust timepieces with tritium vial dial illumination. Since then Luminox has supplied watches to other military and police units, while carving out a niche for itself in the marketplace as a very affordable, military-type timepiece. To mark its 25th year, Luminox has created a pair of limited editions for its key markets in South-East Asia, the Gold Navy SEAL Colormark and the Compass BlackOut. Both are limited to 500 pieces each, and like all Luminox watches are equipped with tritium gas-filled tubes on the dial and hands. Made by Swiss specialist MB-Microtec, these tiny glass tubes emit a unparalleled glow without a need to be charged by an external light source.  The light is emitted due to the tritium gas inside the glass tube, which causes a phosphorescent coating on the inside of the tube to give off light as the tritium decays. Tritium’s half life is about 12 years, so the brightness of the glow will halve in that period.

The first limited edition is the Gold Navy SEAL Colormark, a variant of the watch Luminox supplies to the US Navy Seals. This has striking gold accents on the dial and bezel, providing a striking contrast with the carbon fibre-reinforced polycarbonate case (essentially a very hard plastic).

And the second is the Compass BlackOut, featuring a removable compass on the rubber strap and a compass rose motif on the dial. This too has a carbon fibre-reinforced polycarbonate case.

Luminox watches are eminently affordable, typically costing a few hundred dollars. The 25th anniversary limited editions are similarly priced, with the Compass Black Out priced at 625 Singapore dollars (about US$500), while the Gold Colormark is 595 Singapore dollars (equivalent to US$476). Prices are before taxes.  These watches are only available at Luminox retailers in Singapore, Malaysia and Brunei. More info is available from Crystal Time, the Luminox distributor for the region.
